  1. Magnetism Melissa Nancy Emily

  2. is the attraction of one object for another object Magnetism

  3. material that shows strong magnetic effects Ferromagnetic In this picture: where is the magnet? What objects are ferromagnetic?

  4. Don’t let magnets get close to electrical outlets!Be careful not to pinch your fingers with the magnets! Safety

  5. Use magnets and items in your cups to figure out which objects are ferromagnetic. Activity

  6. Are there any characteristics that give us clues about if a material is ferromagnetic? Question

  7. the region of magnetic force around a magnet Magnetic Field

  8. the area of the magnet where the magnetic effect is the strongest Magnetic Poles In this picture: what part of this magnetic looks strongest?

  9. Magnetic poles that are alike repel each other and magnetic poles that are unlike attract each other.

  10. Magnetic field lines spread out from one pole, curve around a magnet and return to the other pole.

  11. the smallest particle of an element Atom So small, this drawing is only what we think they look like!

  12. Look at this picture, can you predict which material will be magnetic? Which material will be non-magnetic? Question

  13. a cluster of BILLIONS of atoms that are lined up in the same direction Magnetic Domain

  14. In a magnetized material, all or most of the domains are arranged in the same direction.

  15. Magnets are destroyed by disorganizing the alignment of the atoms. This can be done by hitting it hard or heat.

  16. What do you think happens to a magnet if you break it in half? Question

  17. You get smaller magnets! Answer

  18. Do not eat iron filaments!Wash your hands when finished with this project! Safety

  19. 1. Place magnets under a paper and lightly sprinkle the paper with iron filaments2. Record and draw observations Activity

  20. How are these magnets able to levitate? Demonstration

  21. It’s your turn to levitate the magnets Activity
